🧠 Daily Study Log [2025-09-18]
Explored body-type matched exercise idea, reviewed reverse process in diffusion models, and advanced variable engineering & crisis labeling in the Big Contest 2025 project.
💡 Idea
- Proposed a new fitness idea: Body-Match Exercise
- Concept: Different body types may have exercises that fit better or feel more natural.
- Goal: Explore matching frameworks between body composition and exercise types.
📖 Paper Study
- Continued study of Denoising Diffusion Probabilistic Models (DDPM).
- Day 3 – Reverse Process (Denoising)
- Focused on modeling the reverse probability distribution.
- Learned how a neural network approximates the intractable reverse step by predicting noise.
- Training reduces to a simple MSE objective, making diffusion models stable and effective.
🏆 Competition – Big Contest 2025
- Progressed into Week 2 (Variable Engineering & Crisis Definition).
- Tasks completed:
- Designed time-series derived features (lags, moving averages, growth rates).
- Defined and labeled crisis stages (normal, risk, closure).
- Added demographic and commercial area features.
- Finalized dataset structure for next week’s modeling phase.
✅ TL;DR
📍 New fitness idea: body-type & exercise matching
📍 Studied reverse (denoising) process in DDPM
📍 Engineered variables & defined crisis labels for Big Contest 2025 project
